Redesigning of Agarwood Extracting Machine Applying DFMA Principle

Abstract

This paper presents the comparative study of design efficiency of two different designs of agarwood extracting oil machines by performing using the Design for Manufacturing and Assembly (DFMA) method. The DFMA method was used as it is a well-established technique for improving the efficiency of the product leading to minimizing production costs. It also shortens product development time by reducing the number of components in a product. The study used two different designs of agarwood extracting oil machines as a case study. The result shows that the percentage of the design efficiency of existing design model 1 is 9.25%, whereas it is 15% of redesign. Thus, the redesign model 2 is much better as compared to existing design model 1 in terms of its assembly operation and design efficiency. Therefore, the redesign model 2 is greener than existing design model 1. Therefore, the application of the DFMA method to enhance the development of a agarwood extracting product has been proven to be highly useful in the design work.
